Omnicom Media Group elevates Laura Nice and Sian Whitnall to lead PHD and OMD

Omnicom Media Group Australia has made two major internal leadership moves, naming Laura Nice as CEO of PHD Australia and Sian Whitnall as sole CEO of OMD Australia.

The pair previously steered OMD together, delivering double-digit growth and top-tier client satisfaction over four years in one of the most competitive markets in media.

Fresh leadership for a future-fit network

Nice steps into PHD with a brief to accelerate growth and innovation, bringing her trademark blend of commercial sharpness and client-led strategy.

She replaces Mark Jarrett, who’s set to take on a group-level role to be announced in the coming weeks.

Whitnall will continue OMD’s run as Australia’s number-one media agency, according to RECMA, leaning into creativity, collaboration and standout brand experiences to keep clients ahead of the curve.

Building from within

OMG Australia COO Kristiaan Kroon said the appointments signal a commitment to nurturing home-grown leadership as the group prepares for its next chapter under the new Omnicom Oceania structure.

“Laura and Sian exemplify our culture of building leaders who prioritise client success,” he said, noting the shift positions the group to scale its offering and strengthen partnerships across the region.
